Goodman HVAC Package Unit

My goodman package unit wont ignite for heat.  I have reset it several times by cycling the breaker on the outside.  I hear the gas flowing and the plug trying to light.  I hear it clicking a total of three times then the unit shuts off completely.   I had the unit running in the afternoon a few weeks ago and it was working.  I am not sure what could be the problem.

Any suggestions ?

Re: Goodman HVAC Package Unit

Try moving the pilot sensor over closer to the pilot flame, over time they tend to bend and move away from the flame, if this is not sensing the pilot it will not light. It is like a thermocoupler for your gas valve. Let me know if this works.

Re: Goodman HVAC Package Unit

Cycling the external switch on the GMS series will not help you. That switch is for A/C only. At the unit found inside the house, remove the front cover. If there is a door switch, tape it closed. Now if the thermostat is calling for heat, the unit will cycle as you mentioned. When the unit does not start, check for a blinking light on the circuit board. After three unsuccessful tries, the light will blink a code (2 blinks then a pause up to 9 blinks than a pause). Make a note of how many blinks you see. On the reverse side of the access panel you will find a diagnostic schematic. It should tell you a fault code corresponding with your blinking. This will give you a starting point where to look. If the codes are not found there, check inside your owner's manual. Or you can call Goodman at 713-861-250.
Get back to us with those codes and maybe we can help you further.

Package unit outside. thermostat inside calls for heat, have to turn thermostat up about ten degrees over the temp inside to get unit to come on and heat. It will work a few days then wont come on at all....

Yes it could. Probably the Thermostat Transformer in the outside unit. Unless, it's millivolt control. In which case the Thermopile or Thermogenerator, which is part of the Pilot Assembly needs to be replaced. Neither part is expensive, but should be done by a qualified serviceman. That way you'll get the part that has the proper voltage.

There is a induced draft motor that will run first to purge the combustion chamber and induce a draft, a pressure switch closes proving an induced draft exists, thus allowing the spark and pilot gas, or hot surface ignitir and gas to pilot rsil and /or burners, a trial period for ignition about 30 seconds each for 3 attempts will be made and if not lit by the 3rd attempt it locks out, requiring a reset of power to unit to reset the module or circuit board etc. 1st see what motors running, is it the flue exhaust motor/induced draft??

Hi I have commercial hvac goodman unit and trying to change my filter, but i have no idea where the filter is located. the model number is GPG13480903AB

On this package unit, there are no places for filters inside the unit itself unless a technician rigged something up to accept one, but not a common thing at all. These units will use filter return grills inside the building. They are usually 2x2 grills on a dropped ceiling grid or could have a filter grill located right off the return plenum from the unit. Either way, it should be inside somewhere and easy to access. Hope this steers you in the right direction and good luck!

Burner ignites and goes out (Goodman Gas-fired furnace)

The problem you have is water in the exhaust pipe.
Check to see if the pipe has sagged anywhere or if there is a trap in the line.
If you hear gurgling then it is definetly water....
Some times can be hard to find, even a pipe 1/4 full will cause problems. They are very sensitive to flue problems.
Make sure that the flue pipe either runs back to the furnace or out to the outside, a continuos slope either way witha high spot in the middle.
Also check the bottom drain of the blower if it has one, have had them plug and trap water also..

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Goodman 075-3 fan runs but no voltage going to igniter

One thing you can checkmis the continuity through the ignitor itself if you have continutity through that there is also some safeties it has to go through but the board is where the voltage is supplied for the ignitor. I would check the high limit and the roll out before condeming the board.

Goodman unit blows 45 amp fuses only in heat mode, worked fine all summer on a/c. It works well for some time then blows them again.

Check the breakers on the unit How many KW--electric heat? Check to see if you have the right wires wired up to the correct breaker cause some units have 40---and ---60 ---amps breakers and your thickest wire could be wired to the 40-amp breakers,, (some 5 KW pullls 19-23 amps respectably some breakers have 7.5 KW heat stips and pulls more and if the wire size can,t cary the amps, then all you have to do is reduce a heat strip.
